Margo Martindale is readying a fallback plan in the event A Gifted Man fails to see a second season.

The Emmy winner has joined the cast of Counter Culture, ABC’s sitcom pilot about three aging sisters running their family diner together in West Texas. She’ll play the eldest sister, Joyce. Doris Roberts co-stars as coiffed southern belle who runs the cash register at the diner.

The pilot is in “second position” to Martindale’s current gig, CBS’ A Gifted Man, which airs its season finale this Friday and is considered a long-shot for renewal.

Showtime, meanwhile, announced Wednesday that Martindale will appear as a guest star in Masters of Sex, a drama pilot about 1960’s human sexuality pioneers William Masters (Michael Sheen) and Virginia Johnson (Lizzy Caplan). Martindale will play Masters’ secretary, Miss Horchow.
